Application filed May 3, 1909. Serial No. 493,467. i

To all whom it'may concern:

Be it known that I, IzIDoR BUGHLER, a subject of the Emperor of Austria-Hungary, residing at the city of New York, in the county of New York and State of New York, have invented certain new anduseful Improvements in Stropping-Machines, of which the following is a specification.

My invention relates to that class of razorstropping machines in which a looped strop bears against a'shaft, which is oscillated as the two ends of the strop are pulled back and forth and causes a razor holder to move from side to side.'

The object of the invention is to simplify the construction of such stropping machines andv at the same time to attain a high degree of durability and eiiiciency. Y

To this end the invention may be said to consist in the various novel features and an rangements of parts set forth in the appended claims and fully described in the fol-` lowing speciflcation. A

In the accompanying drawings, Figure 1 isa side view of the improved stropping machine; Fig. 2 is an end view; Fig. 3 Vis a View of the-,other'end of the device; Fig. 4 is a section corresponding to Fig. 1, being on an enlarged' scale; and Fig. 5 is an enlarged end view; y f

Referring now'to these views, the numeral 1 designates the framework of the device yas a whole. One of the features of the invention resides 'in the simple, yet strong and effective construction of this framework. It comprisesprimarily a top frame 2 and two side frames 3. .The top frame y2 consists simply of a metalV plate, having its end portions 4 bent downward at substantially-right angles.. rlhe side frames3 are pivotally or hingedly connected, in spaced relation, near their upper ends, to the lower portions of these end portions 4. Each side frame 3 consists preferably of two substantially L- shaped plates 5,' the upper ends of which are pivoted as described, at 6, to the end portions 4 ofthe top frame Q-,and which are united by two rods 7 and 8, connecting, respectively, the side and bottom bars of the L-shaped plates 5 These rods 7 and 8 serve also as guidesforthe strop 9, the ,two portions of which are' threadedf 'between the4 members of the two pairs'of rods. In operation, the strop 9 bears against the outer sides of the rods 8, which, obviously, might be in the form of rollers; and the rods 7 might,

.if desired, 'be omitted. The inner ends of the bottom bars of the L-shaped plates 5 abut against each other, when the framework is closed, whereby there is afforded a suHicient opening through from end to end of the framework for the accommodation of the razor. To insure that the framework will not open lat an inconvenient moment, a yielding catch may be employed to connect said side frames 3. vA simple form of such catch is illustrated in the form of a resilient yplate 10, secured to the inner face of the L-shaped plates 5, one or both of ythesaid.

L-shaped plates may be provid-ed above. the pivots 6 lwith hooks or extensions 13 that bear against studsor projections 14 ron the i inner surfaces of the plates 5.V YTheseexteusions 13 may serve, on the other hand, to limit the degree of opening of theside frames 3. by contacting with any suitable stop, as the enlarged end 15 of the shaft 16 of the razor-holder-17. The strop-9 is looped about an actuating shaft 118 journaled in the end portions 4 of the top frame 2. This shaft is geared to the shaft 16 below, as by mutilated spur gears 32. The razor-holder 17 is carried by the shaft 16, and has converging side walls 19, spaced apart slightly at the bottom. "Between these walls the razor blade is slipped-end'- wise, and is held in position by a bowed spring 20 secured to `the inside of the top of the'holder. One end 'of the spring 2O is preferably bent downward, as at 21, to constitute a stop against whichthe end of the razor blade abut-s.r It will .be obvious .that the razor-holder might be constructed to hold the blades of safety irazors.

An important feature of the invention resides in the provision of a detent carried or otherwise actuated by yielding supporting means for the framework l, whereby the detent is normally in locking relation with respect to the razor-holder but is moved to release the razor-holder when pull is eX- erted on the ends of the strop. Naturally there may be numerous embodiments of this detent. A desirable form is illustrated, in which a sliding bar or plate 22 extends between the portions 4 of the top plate 2, the ends 23, 24 of this bar being reduced and moving in vertical slot-s 25 in the portions 4 of the plate 2. The end part 223 of the bar 22 constitutes the detent proper, heilig designed to engage with a suitable socket 26 formed in an enlargement or plate on one end of the actuating shaft 1S. However, the detent lnight well engage with another part, if desired. 'The detent is held normally in engagement with the socket by means of a spring or springs 27. interposed between the plate 2 and the bar 22. These springs are desirably coiled about guiding posts 28 secured to the plate 2 and passing through openings 29 in the bar 22. A hanging hook or eye 30 is secured to the bar 22 and pron jects upward through an opening 31 in the top plate 2. The bar 22 also serves to brace the top frame 2. Thus, the razor-holder is normally held stationary, so that danger of cutting, through wabbling of the holder, when the razor is being inserted or removed, is eliminated. When the device 30 is secured to any suitable anchorage and pull is exerted upon the ends of the strop, the whole framework 1 is drawn downward or outward with respect to the bar 22, so that the detent is released, and-reciprocation of the strop results in the razor-holder being swung from side to side in cooperative relation with the successive out-going portions of the strop. rThe resilient support of the framework of the machine is of advantage in affording an easier stropping action.

While the preferred embodiment of theV invention has, for sake of clearness, been described in considerable detail, it will be obvious that numerous changes may be made without departing from the scope of the invention.
